Some other things I've contributed to

I reverse-engineered some of the Napster protocol and wrote one of the
first third-party clients. I was soon hired to help design a Napster
clone called Scour Exchange. Few people even remember these sites
now.

On a drunken dare I made a Windows-native theme engine for GTK. It
eventually morphed, after removing all my bad code, into the standard
Windows GTK theme.
